If there's an unofficial mascot for Halloween, it's Heidi Klum. Over the years, the model turned TV host has become synonymous with the holiday as she's continuously one-upped her costume each year. Her dedication to Halloween is so inspiring, it was the definition of goals long before that word became an internet hyperbole. This year, however, Heidi set a new record—she didn't just have one costume, she had six.

Her costume was so elaborate it required five other people to dress up with her: she went as a flashy version of herself with five clones, for those who didn't see the epic reveal that unfolded on her Instagram throughout most of Halloween. While the choice might have seemed low-maintenance compared to her makeup and prop-heavy past costumes, it didn't come cheap.

According to her makeup effects artist Mike Marino of Prosthetics Renaissance, Heidi spent a whopping $10 million. No your eyes aren't playing tricks on you. (For the record, that's more than Kylie Jenner spent on a recent house.)

That was the sum he offered to TooFab. How exactly would someone rack up that kind of bill for Halloween? Heidi had to make a Lifecast of her face, which Marino and his colleague used to create prosthetic masks for the five girls. Then they had to affix them, using "DermaFlage silicone to fill any gaps in the mask," which required about two hours per person. On top of that, Heidi and co. required makeup, hairstyling, and clothing. Still, $10 million?

As it turns out, Marino wasn't planning on revealing the full amount. "We can never give full details on payment, so we'll leave it up to your imagination!," said a rep from Prosthetic Renaissance when pressed by TooFab.

Either way, Halloween isn't the easiest holiday to skimp on — this year saw record spending by Americans on everything from costumes to decor and candy. Heidi Klum clearly wasn't alone.
